Speaking of "service."

A priest walked into a barber shop in Washington, D.C. After he got his haircut, he asked how much it would be.
The barber said, "No charge. I consider it a service to the Lord."
The next morning, the barber came to work and there were 12 prayer books and a thank you note from the priest in front of the door.
Later that day, a police officer came in and got his hair cut. He then asked how much it was.
The barber said, "No charge. I consider it a service to the community."
The next morning, he came to work and there were a dozen donuts and a thank you note from the police officer.
Then, a Senator came in and got a haircut. When he was done he asked how much it was.
The barber said, "No charge. I consider it a service to the country."
The next morning, the barber came to work and there were 12 Senators in front of the door.
